Struct ServiceProvider 

pub struct ServiceProvider { /* private fields */ }

Implementations

impl ServiceProvider

pub fn register_disposable(&self, cleanup: Box<dyn FnOnce() + Send>)

Register a cleanup closure for a scoped service.

Called by users who want to ensure their scoped services are cleaned up deterministically when the scope ends. The closure is invoked when Self::dispose_scoped is called (via Scope::dispose or Scope Drop).

pub fn get<T: ?Sized + Send + Sync + 'static>(&self) -> Result<Arc<T>, RdiError>

Resolve a service by type. Works uniformly for concrete types and trait objects. Returns Err(RdiError::ServiceNotFound) if not registered.

pub fn get_optional<T: ?Sized + Send + Sync + 'static>(&self) -> Option<Arc<T>>

Resolve a service by type, returning None if not registered.

pub async fn get_async<T: ?Sized + Send + Sync + 'static>( &self, ) -> Result<Arc<T>, RdiError>

Resolve an async service (transient or scoped) by type.

• Singletons are resolved synchronously (already cached during build_async).
• Scoped services are cached in root_scoped_cache (one instance per scope).
• Transient services call the async factory fresh each time.

pub async fn get_keyed_async<T: ?Sized + Send + Sync + 'static>( &self, key: &str, ) -> Result<Arc<T>, RdiError>

Resolve an async keyed service by type and key.

pub fn get_keyed<T: ?Sized + Send + Sync + 'static>( &self, key: &str, ) -> Result<Arc<T>, RdiError>

Resolve a keyed service by type and key. Returns Err(RdiError::KeyedServiceNotFound) if not found.

pub fn get_owned<T: Send + Sync + 'static>(&self) -> Result<T, RdiError>

Resolve owned T (bypass cache, fresh each call). Returns Err if not registered or the service is Singleton.

pub fn try_get_owned<T: Send + Sync + 'static>(&self) -> Option<T>

Resolve owned T, returning None if not registered or Singleton.

pub fn get_keyed_owned<T: Send + Sync + 'static>( &self, key: &str, ) -> Result<T, RdiError>

Resolve owned keyed T. Returns Err if not found or Singleton.

pub fn try_get_keyed_owned<T: Send + Sync + 'static>( &self, key: &str, ) -> Option<T>

Resolve owned keyed T, returning None if not found or Singleton.

pub fn get_all<T: ?Sized + Send + Sync + 'static>(&self) -> Vec<Arc<T>>

Return all registered instances of the given type.

pub fn scope(self: &Arc<Self>) -> Scope

Create a new service scope.

Analogous to IServiceProvider.CreateScope() in MEDI. Scoped-lifetime services are cached within the returned scope.

pub fn get_named<T: Send + Sync + 'static>(&self, name: &str) -> Option<Arc<T>>

Cross-DLL safe named service resolution (generic).

pub fn get_named_any(&self, name: &str) -> Option<Arc<dyn Any + Send + Sync>>

Non-generic named resolution; returns Arc<dyn Any> for trait-object dispatch.

pub fn register_named<T: Send + Sync + 'static>( &self, name: &str, service: Arc<T>, )

Register a named service for cross-DLL plugin access.

pub fn remove_named(&self, name: &str)

Remove a named service (for plugin unload).

pub fn rdi_register_named( &self, name: &str, service: Arc<dyn Any + Send + Sync>, )

Register a named service (for IProvider trait).

pub fn rdi_remove_named(&self, name: &str)

Remove a named service (for IProvider trait).
